[0023] The specific settings and functions of the cleaning device 5 and the auxiliary device will be described in detail below.

[0024] Specifically, the cleaning device 5 includes a rotating cover 51, which is rotatably connected to the inside of the tank cover 2. A water inlet ring 55 is fixedly connected to the lower surface of the rotating cover 51, and a water inlet pipe 54 is fixedly connected to the surface of the water inlet ring 55. One end of the water inlet pipe 54 is connected to the rotating cover 51 through the lower surface of the water inlet ring 55 through water pipes. A control component 1 52 is provided on the surface of the rotating cover 51, and a control component 2 53 is provided between the rotating cover 51 and the nozzle 56.

[0025] In this embodiment: when cleaning, water can be supplied to the water inlet ring 55 through the water inlet pipe 54, and then the water inlet ring 55 outputs water to the nozzle 56 through the water pipe. The nozzle 56 sprays out water at high pressure for cleaning. Through the control component 1 52, the whole can be driven to rotate and spray, and the control component 2 53 can control the nozzle 56 to switch the angle of spraying.

[0026] Specifically, the control component 1 52 includes a transmission head 1 522, which is fixedly connected to the surface of the rotating cover 51, and the surface of the tank cover 2 is fixedly connected to a motor 521, and the output end of the motor 521 is fixedly connected to a transmission head 2 523, and the surfaces of the transmission head 1 522 and the transmission head 2 523 are installed with a transmission belt 524.

[0027] In this embodiment: when driving the whole to rotate and spray, turn on the motor 521, the motor 521 drives the transmission head 1 522 and the rotating cover 51 to rotate through the transmission head 2 523 and the transmission belt 524, and the rotating cover 51 drives the water inlet ring 55 and the spray head 56 to rotate, driving the rotating cover 51 to rotate within 0-90 degrees.

[0028] Specifically, the control component 2 53 includes a fixed frame 536, which is fixedly connected to the surface of the rotating cover 51, and a cylinder 531 is fixedly connected to the surface of the fixed frame 536. A rack 532 is fixedly connected to the output end of the cylinder 531, and the rack 532 is through-connected with the rotating cover 51 and the water inlet ring 55. A positioning frame 535 is provided on the surface of the water inlet ring 55 close to the nozzle 56, and a rotating shaft 534 is rotatably connected to the inner wall of the positioning frame 535. The nozzle 56 is fixedly connected to the surface of the rotating shaft 534, and a gear 533 is fixedly connected to the surface of the rotating shaft 534. The rack 532 is meshed with the gear 533. When the nozzle 56 is controlled to switch the angle, the cylinder 531 is opened, the cylinder 531 drives the rack 532 to move, the rack 532 drives the gear 533 to rotate, and then the rotating shaft 534 drives the nozzle 56 to adjust the angle.

[0029] Specifically, a filtering device 6 is provided on the surface of the feed pipe 4, and the filtering device 6 includes a collecting pipe 61, which is provided at one end of the feed pipe 4, and a filter element 64 is fixedly connected to the inner wall of the collecting pipe 61, and a threaded end 65 is fixedly connected to the surface of one end of the collecting pipe 61, and the threaded end 65 is threadedly connected to the inner wall of the feed pipe 4.

[0030] In this embodiment, the threaded end 65 can be threadedly connected to the inner wall of the feed pipe 4 to install the collecting pipe 61. Then, the filter 64 can filter impurities in the collecting pipe 61 to reduce the impurities entering the evaporation tank body 1, which is convenient for subsequent cleaning.

[0031] Specifically, a handle 62 is fixedly connected to the outer surface of the collecting tube 61 , and there are three groups of handles 62 . The collecting tube 61 can be more conveniently controlled to rotate through the handle 62 , thereby performing a disassembly operation.

[0032] Specifically, one end of the collecting pipe 61 is fixedly connected with a flange 63 .

[0033] In this embodiment, the flange 63 facilitates the connection of the collecting pipe 61 with other pipelines.

[0034] Working principle: When the equipment is in use, when waste water enters the feed pipe 4, the collection pipe 61 cooperates with the filter element 64 to intercept impurities in the waste water, and then the collection pipe 61 collects the impurities to reduce the impurities entering the evaporation tank 1, which causes the phenomenon of attachment and subsequent inconvenience in cleaning. When cleaning is required, the water inlet pipe 54 is first connected to the water supply part, and the water inlet pipe 54 supplies water to the water inlet ring 55 and the nozzle 56, and then the nozzle 56 sprays water with high pressure for flushing. At the same time, the cylinder 531 can be opened, and the cylinder 531 drives the rack 532 to move upward or downward, and the rack 532 drives the gear 533 to rotate, and the gear 533 then The rotating shaft 534 drives the nozzle 56 to adjust the angle, allowing the nozzle 56 to swing up and down for flushing, and then the motor 521 can be used. The motor 521 cooperates with the transmission head 2 523 and the transmission belt 524 to drive the transmission head 1 522 and the rotating cover 51 to rotate. The rotating cover 51 drives the water inlet ring 55 and the nozzle 56 to rotate back and forth between 0-90 degrees, thereby achieving comprehensive high-pressure flushing of the nozzle 56. When disassembling the collecting tube 61, it is only necessary to drive the collecting tube 61 and the threaded end 65 to rotate through the handle 62, so that the threaded end 65 loses contact with the feed tube 4, and the collecting tube 61 is removed for cleaning.
